Using the Illinois Planning Index
The value of 98 is one location input in the CostSignals internal model. Its difference from 100 is expressed in index points. Without a documented source tuple and verified date, the value must not be interpreted as an observed state price level or a precise adjustment to a project budget.
Start with a calculator that matches the work, enter the project dimensions and options you know, and treat the result as a planning scenario. Compare it with written quotes that define the same scope before making a hiring decision.
Project-planning checklist:
- Write down the project scope, quantities, materials, and exclusions
- Use calculator results as scenarios rather than bids or offers
- Request comparable written quotes from qualified local professionals
- Verify applicable permits, licenses, and insurance with the relevant authorities
